Any way to hide and arrange the extensions in any kind of warper or something

You are about to read some bad English and I am really sorry about it I am not a native English speaker. [url=https://i.imgur.com/DmiTycC.png]I have many extensions[/url] but in Vivaldi as we all know we can't even arrange our extension's nor we can hide them in some kind of warper like in chrome all the extension can be hide in the menu I want something like that ! Is there is anything we can do with the help of CSS+JS 2nd this is there is anyway we can add setting button on extension like [url=https://github.com/justdanpo/VivaldiHooks/blob/master/screenshots/extensions-buttons-menu-settings.png]this[/url]

Rearranging is not possible yet (but I think it'll come, it was asked several times).
For hiding icon, but keeping extension enabled, you can just do with right click on it.
For the setting button on extension, you should ask in the thread about vivaldi hooks (modifications css/js): no native option for that yet.
You can try to hide and group extensions via an additional extension.
